Common Terms
(and what they mean)

C or Socket: A regular hub or socket. The pipe fits (sweats/solders) inside this

Mips: Male pipe threads on the outside of fitting

Fips: Female pipe threads on the inside of fitting

FTG: The same size as the pipe. Will fit inside a socket (hub) fitting

Hyset: Has a nailing flange on the front of the fitting

Dropear: Has a nailing flange on the back of the fitting

Nominal: Used to describe copper pipe and fittings in plumbing. Refers to the inside diameter of the pipe which varies by thickness of the pipe. The outside is a constant size and is always 1/8" larger than the nominal size. Example: 1/2" nominal is always 5/8" O.D.

Back To Top Of Page

"I have 1/2" copper fittings, can I use 1/2" o.d. copper tubing with those fittings?"
Probably not. In the plumbing trade when we say 1/2" fittings we mean fittings that use 1/2" nominal pipe. To figure what size pipe to use with standard plumbing fittings, you must add 1/8" to your measurements to know the o.d. (outside diameter) of the pipe. 1/2" nominal fittings use 5/8" od pipe; 3/4" fittings uses 7/8" pipe and so on.

"What is CA AB 1953 and VT S.152 and how is this different from previous low-lead legislation?"
The United States Environmental Protection Agency (EPA) regulates the amount of lead in drinking water under guidelines established in the Federal Safe Drinking Water Act (passed in 1974; amended in 1988 and 1996). This Act defines "lead-free" as not more than 8% lead in pipes and fixture fittings. PLEASE NOTE: Use of the term "lead-free" varies between the new legislation in CA (AB 1953) and VT (S.152), and in the current Federal Safe Drinking Water Act requirements. In the new legislation for CA and VT only, starting in 2010, it will mean 0.25% or less (weighted average).
